SEWING-MACHINE FOR MAKING EYELETS.

SPECIFICATION forming part of Lettere Patent No. 626,815, dated June`1a, 1899.

Application led December 27, 1897. Serial No. 663,631. (No model.)

To ,ctZZ whom it may concern.-

Beit known that we, JOHN MORTON and WILLIAM URIE MoRToN, sewing machinemanufacturers, of Bothwell Circus, Glasgow, in the county of Lanark,Scotland, have invented certain new and useful Improvements inSewing-Machines, (which have been patented in Great Britain by LettersPatent, dated August 15, 1891, No.13,775,) of which the following is aspecification.

The invention relates to machinery for sewing rings or gromets intosails, tarpaulins,

awnings, tents, wagon-covers, horse-clothing, and other coverings, themachine being also applicable for making eyeholes-zl e., edgesholes-without using a ring or gromet.

The invention is illustrated by the accompanying drawings.

Figure 1 is a side elevation, partly in section, of a machine embodyingthe invention; and Fig. 2, a front elevation of part of the same. Fig. 3is a sectional view of the needlebar tube with its internal gear Fig. 4,a plan of the clamping device, and Fig. 5 a sectional view showing theneedle-plate.

1 represents the machine-bed.

2 is the arm; 4, the needle-shaft; 5, the cam on needle-shaft whichoperates the'toothed wheel 6 on the vertical shaft 7, and 8 is thespur-wheel at the lower` end ofv said shaft.

The cam 5 may be described as a worm having a single ridge 3 on itscircumference, and as the needle-shaft 4 brings this part around itturns the toothed wheel 6 the distance of one tooth. The spur-wheel 8causes the parallel vertical shaft 9 to revolve by engaging with thespur-wheel 10.

11 and 12 are bevel-gears at the upper and lower ends of the shaft 9.The horizontal shaft 13 passes through the machine-arm and obtainsmotion from bevel-gear 11 through the medium of an exactly similar gear14. On the opposite end of thehorizontal shaft 13 is another bevel-gear15, which turns the needle-bar tube 16 by engaging with the bevelgear17.

The horizontal shaft 1S, which passes under the machine-bed, has at itsright-hand end bevel-gear 19, which obtains motion from the bevel-gear12. On the left-hand end of the shaft 18 there is a bevel-gear 20, whichenplate 62.

gages with another gear 21, fixed to shuttleshaft 22.

On the yneedle-shaft 4 there is an eccentric 23, whose connecting-rod 24is coupled to one end of a rocking lever 25, the other end of thisvrocking lever being forked and fitted with rollers which fit into agrooved collar 26. The collar 26v encircles lthe shuttle-.shaft 22 and,being loose on said shaft, allows the vshaft to revolve within it. Thegrooved collar 26 rises and falls in obedience to the rocking lever 25and carries with it a link 27, which connects said collar to abell-crank 28. of said bell-crank is marked 29 and forms theshuttle-lever, the shuttle-carrier 30 being fixed thereto. The upper endof the shuttleshaft 22 is attened, as at 60, and on this is carried thestud 61," on which the bell-crank oscillates. To the fiat part of theshuttleshaft there is also fixed a circular plate 62,

and as the shuttle-shaft 22 revolves it is kept from swaying by rollers63, of which there are The long arm four,bearing at equal distances onthe circular The rollers 63 are sustained by a bracket 64, which isbolted to the machinebed 1. It will thus be clear that the shuttlelever29 reciprocates as the eccentric 23 moves around with the needle-shaft 4and that as the shuttle-shaft 22 is revolved the path of the shlittle-lever 29 must always be in aline which constitutes adiameter ofthe circular plate.

The needle-bar tube, with its connections, is detailed at Fig. 3. israised and lowered by a heart-shaped cam fixed to a block 32, whichclasps the needlebar tube and carries it up and down, this arrangementbeing a well-known device used in raising and lowering the needle-bar inordi- The block 32 is an The needle-bar tube 1G iron casting having ahole bored perpendicularly through it to allow the needle-bar tube 16 torevolve within it, and the block 32 raises and lowers the needle-bartube by acting on collars 65 and 66, which -are iixed to the needle-bartube and revolve with it. A doublegrooved cam 37, secured on the frontend of the needle-shaft 4, acts as a-disk as well as a cam, havingon itsface a stud carrying a roller, said roller working in the heart-shapedcam to carry the block 32 and the needle-bar tube 16 up and down as theneedle-shaft 4 IOC rotates. The needle-bar or cross-head 31, to

which the needle is attached, moves transversely of the needle-bar tube16 in a slot therein, as shown particularly at Fig. 3, being retained inthe'slot by a plate 33', secured to the bottom of the tube 16, the baror cross-head 31 having an inclined slot 34.

35 is a bar which passes within the needlebar tube 16 and lower end ofsaid bar being furnished with' a stud which Works vin the inclined slot34 in the cross-head 31 and the upper en'd being provided with a pinwhich is acted on in the manner hereinafter described, so that as saidbar rises and falls the needle 36 is alternately thrown out and in, soas to take one stitch inside and the next outside the gromet or eyehole,as shown particularly at Fig. 5. The bar 35 is caused to move up anddown by means of the doublegrooved cam 37, fixed on the needle-shaft 4.The'dou'ble-grooved cam 37 may be described as a cylinder with twocircumferential grooves cut in it and .having a fixed switch at onepoint of its circumference, so that the gib whichis attached to a bar3S, being pointed and following in the aforesaid grooves, is movedalternately from one groove to the other as the needle-shaft 4 revolves.The bar 38 is supported by brackets 59, pi'voted at 67, and as the gibbefore mentioned follows to either groove of the double-grooved cam 37the bar 33 imparts motion to the lower arm of a bell-crank lever3), theother arm of the bell-crank being forked to embrace and impart motion toa grooved collar 40, which surrounds the needle-bar tube 1G. This collar40 receives in a recess on its inner surface the pin of the bar 35,which pin extends through a slot GS in the metal tube 1G. Vhen thecollar 40 is moved up and down by the action of the bell-crank lever 39,the bar 35 is caused to act on the inclined slot 34 of the cross-head 31and traverse this needle to the outer and inner side of the gromet oreyehole. A

The needle-bar tube, as shown at Fig. 3, allows free passage for thethread at 45, and thus prevents twisting.

The take-up lever 4o' is fastened to the needle-bar tube 1G and isconnected by a link 47 to a grooved collar 48, which encircles theneedle-bar tube and revolves with it, but is kept from moving n p anddown with it by the arms 49.

The clamp device consists of a ring 50, hinged at its periphery to theforked end of a vertical rod 52, guided on the machine-arm at 51,and-this rod is raised when a gromet or eyehole has been sewed by oneend of a double-ended lever 58, the other end of this lever being actedupon by a cam-piece 59, actuated by a handle 70, the clamp beingnormally held upon the cloth by the action of a spring 57. rlhe ring 50can be turned out of the way transversely of the machine after beingraised by means of a handle 53 upon the vertical rod 52. The ring 50 maybe provided With teeth or spikes on its under side in order to keep thecloth from turning. As shown at Figs. 4 and 5, the ring 50 has a iiangeon which rests the flat circular plate 54', kept from rising by thecatches 55 and turned With the shuttle-shaft 22 by means of a projectingpart 71 of the needle-plate 5G passing through it.

The rotating needle-plate (shown at Fig. 5) is constructed as follows:56 is the needleplate, which is made circular and screwed to the top ofthe shuttle-race 57, said race being fixed to the shuttle-shaft22. Bypreference the needle-plate 5G is formed with a recess 72, in which thering or gromet lies; but it may be used Without, and in making eyeholesno recess is necessary.
